Jackson Mac Low (September 12, 1922 – December 8, 2004) was an American poet, performance artist, composer and playwright, known to most readers of poetry as a practioneer of systematic chance operations and other non-intentional compositional methods in his work, which Mac Low first experienced in the musical work of John Cage, Earle Brown, and Christian Wolff. He was married to the artist Iris Lezak from 1962 to 1978, and to the poet Anne Tardos from 1990 until his death. An early affiliate of Fluxus (he co-published An Anthology of Chance Operations) and stylistic progenitor of the Language poets, Mac Low cultivated ties with an eclectic array of notable figures in the postwar American avant-garde, including Nam June Paik, Kathy Acker, Allen Ginsberg, andArthur Russell. His work has been published in more than 90 anthologies and periodicals and read publicly, exhibited, performed, and broadcast in North and South America, Europe, Japan, Australia, and New Zealand. He read, performed, and lectured in New York and throughout North America, Europe, and New Zealand, San Francisco, Santa Cruz, Asnières, Paris, Bouliac (near Bordeaux), Marseilles, Buffalo, Philadelphia, and New York.
